Strange menu problem

I have the strangest thing and cannot seem to find out where the problem lies.

My menu item home does not work in Firefox. Everything works fine in IE (that's a first :-))

I have gone over and over my css, but i just cannot see what the issue is...
Hopefully someone can tell me what i am doing wrong!

not entirely sure why , but your div <div id="rozet"/> covers the home button and prevents it triggering.
Maybe z-index the button to the front? or move rozet left?

oooooohhhh! Thanks a lot!!!

Why didn't I think of that...
